Fluid-Filled Frequency-Tunable Mass Damper

Innovators at Marshall Space Flight Center developed the fluid-filled Frequency-Tunable Mass Damper (FTMD) technology that allows for significant distribution of loads while also providing a simple mechanism that allows for the capability to change its frequency of mitigation with negligible impact on...

Supersonic flight over land is generally prohibited because sonic booms created by shockwaves disturb people on the ground and can damage property. Armstrong innovators are working to...

A new device, inspired by a rose, inexpensively collects and purifies water. The device is a new approach to solar steaming for water production — a technique that uses energy from sunlight...

Miniature Stretchable Pump

Soft robots have a distinct advantage over rigid robots: they can adapt to complex environments, handle fragile objects, and interact safely with humans. Made from silicone, rubber, or other stretchable polymers,...

Unlike water, liquid refrigerants and other fluids that have a low surface tension spread quickly into a sheet when they come into contact with a surface. For many industrial...

Mini Stretchable Pump for Soft Robots

Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines’ moving parts. Because they are connected to these bulky pumps by tubes, these robots have limited autonomy...

Millions of gallons of crude oil were released into the Gulf of Mexico during the seabed oil drilling catastrophe of 2010. Numerous strategies to stop or stem the oil flow...

Conventional pistons are made of a rigid chamber and a piston inside that can slide along the chamber’s inner wall while at the same time maintaining a tight seal. As a result, the piston...

Certain species of bacteria that exist in oxygen-deprived environments must find a way to breathe that doesn't involve oxygen. These microbes — which can be found deep within mines, at...

Visualizing Motion of Water Molecules for Liquid-Based Electronics

A high-resolution inelastic x-ray scattering technique was used to measure the strong bond involving a hydrogen atom sandwiched between two oxygen atoms. This hydrogen bond is a quantum-mechanical phenomenon responsible for various properties of water, including viscosity, that...

Cryogenic Hydraulically Actuated Isolation Valve

Researchers at NASA's Marshall Space Flight Center have developed a cryogenic isolation valve that utilizes the upstream line pressure of cryogenic fluids for actuation. Previously, the use of cryogenic fluids for actuation systems had been too difficult to control and resulted in unsafe operating...

Nitinol-Actuated, Normally Open Valve Assembly (NOVA)

NASA Goddard Space Flight Center has developed the NOVA zero-leak, permanent isolation valve that helps prevent leaks in space propulsion systems with operating pressures less than or equal to 500 psia. The actuator is made from nitinol, a heat-activated, non-explosive, shape memory alloy and...

A new method uses ultraviolet light to control the flow of fluids by encouraging particles — from plastic microbeads, to bacterial spores, to pollutants — to...

Light-Activated Micro-Pump

Even the smallest mechanical pumps have limitations, from the micro-fabrication techniques required to make them to the fact that there are limits on their size. A laser-driven photoacoustic microfluidic pump was...

Microscale Electro-Hydrodynamic (EHD) Modular Cartridge Pump

The EHD pump uses electric fields to move a dielectric fluid coolant in a thermal loop to dissipate heat generated by electrical components with a low-power system. The pump has only a few key components and no moving parts, increasing the simplicity and robustness of the system. In...
